1. The new children's hospital will provide in-patients with their own single room and en-suite bathroom, with overnight in-room accommodation for parent

2. The new theatres and procedure rooms will have advanced medical technology for patient diagnosis (e.g. x-ray machines) and complex surgeries, which will improve clinical outcomes for patients.

3. €200m would be made available for the new children’s hospital from the sale of the National Lottery, adding to the existing €450 million Exchequer funding. But rising costs in the construction sector will push up that bill.

4. The plan in 2005 was to close the three existing children's hospitals housed in outdated facilities in Dublin and bring them all under one roof in a state-of-the-art building which would open its doors in 2012. The opening date was then pushed back to 2014 and again, more recently, to 2016.

5. It was turned down for planning permission at the Mater Hospital site in 2012.

6. Major concerns remain among many groups about access to the hospital via car and being caught in traffic.

7. There was a strong lobby to build it on the site of Connolly Hospital in Blanchardstown.

8. There will be car parking facilities for less than a fifth of the 5,000 staff in the St James’s Hospital campus upon completion of the proposed new national children’s hospital on the St James’s site, according to planners.

9. St James’s Hospital currently has parking capacity for over a third of the 3,000 core staff who work within the site. Despite the addition of 2,000 extra staff who will be employed by the new children’s hospital, proposals are in place to reduce the number of designated parking spaces from 1,100 to 880.

10. Some residents have complained that such a policy will lead to a drastic reduction in on-street parking space in the surrounding area as staff seek alternative options. However, those in charge of the project say an expansion of the €1-an-hour pay parking zone in the locality will discourage car commuters while prompting more employees to walk, cycle or take public transport to work.
